| titleOfInvention | Device and process for co-production of pentafluoroethane from tetrafluoroethylene |
| abstract | The invention relates to the technical field of fluorine chemical industry, in particular to a device and a process for co-producing pentafluoroethane from tetrafluoroethylene. The device comprises a tetrafluoroethylene production device, a tetrafluoroethylene No. 1 rectifying tower, a tetrafluoroethylene No. 2 rectifying tower, pentafluoroethane reaction and separation integrated equipment, a recovery tower, a light component removal tower, a product rectifying tower and a tetrafluoroethylene rectification release gas conveying pipeline; the tetrafluoroethylene rectification release gas conveying pipeline is connected with a tetrafluoroethylene No. 1 rectifying tower and pentafluoroethane reaction and separation integrated equipment. Rectification release gas released from the tetrafluoroethylene rectification tower No. 1 enters pentafluoroethane reaction and separation integrated equipment through a tetrafluoroethylene rectification release gas conveying pipeline to react with hydrofluoric acid to generate pentafluoroethane. According to the invention, the tetrafluoroethylene device is used for rectifying the released gas to produce pentafluoroethane, so that the load of a compressor and a rectifying system is reduced, the production energy consumption is reduced, the process route is optimized, the running of the tetrafluoroethylene device is stabilized, and the optimized utilization of resources is realized; the obtained tetrafluoroethylene and pentafluoroethane have high purity. |
